CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 361,802, dated April26, 1887.

Application filed March 27, 1886. Serial No. 196,838. (Modehl T at whom,it 11mg concern.-

Be it known that I, PHILIP .YoE, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented a certain new and useful Improvement in Cash-Registers; and Ido hereby declare thatthe following is a full, clear, and exactdescription'of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to theletters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in cash-registers, the severalfeatures of which will be fully hereinafter set forth.

The mechanism is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of the cash-register. Fig. 2 is afront-elevation of the same.

A is the base, to which may be attached a suitable form of case, theonly requisite being that orifices must be provided in the case, throughwhich may be seen the figures on the two wheels on which numerals areimpressed.

Bis the metallic frame of the machine, which is alike on both sides,withthe exception of the arresting-arm H,which is on the near side.

O and O are shafts, which are fixedly held in the posts of the frame andare secured by screws. On the shaft 0 is supported the computation-wheelD, on which it freely turns.

On the peripheral face of this wheel is a spiral rib, 0, which forms acontinuous groove over the peripheral face of said wheel. This groove isuniformly spaced and numbered to suit different kinds of business. For acigar-store the numbers may be 5, 10, 15, 850., and for other purposesthe units would be marked. The ratchet-wheel E is fixedly attached tothe hub of the wheel D,with an intervening space between the two. Theteeth on this ratchetwheel correspond exactly with the numbered spaceson the computation-wheel D. Coven ing the lower portion of theperipheral face of this wheel is the shield L, in which is supported theslide N ,which has an opening near the right end,thr ough which a numberon the computation-wheel D may be seen. This slide has areal-wardprojection, s, which enters the groove of the computation-wheel, andwhich (as the machine is operated) causes the slide to move from rightto left across the face of said computation-wheel, and thereby exposes anumber successively as the machine is rotated. On the shaft O,externalto the ratchetwheel, is the arm I,whioh carries a series ofpush-buttons, 5, l0, and 15, which can be pressed through openings inthe arm I to engage the arm H, but are normally held, as shown in Fig.2, by coiled springs. To a lug of this arm is pivoted the pawl-leverP,which engages the ratchet-wheel E, and the opposite end lies upon theright-hand end of the lever K, to which the weight J is attached. Thisweighted lever carries the shutter 11 and forces the pawl :0 intoengagement with the ratchetwheel E by raising the back end thereof. Thepawl atac prevents the computation-wheel from moving in more than onedirection. The plate V serves as a spring-brake,bearing against the sideof the ratchet-wheel, and serves to throw the point of theoperating-pawl I" above the teeth of the ratchet-wheel E,to permit thebackward movement of the same, and in the forward movement of this pawlthe inner beveled edge of the same acts to throw it off from thisplateto the teeth of. the ratchet-wheel.

On the rear posts of the frame and on the fixed shaft 0 is mounted thewheel D, which freely turns thereon, and on the peripheral face of whichare marked numbers on spaces conforming to that of thecomputation-wheel. These numbers ordinarily will answer to fractionalparts of a dollar. To the side of this wheel is attached the pinionG,which engages the rack-bar F, which at its forward end is pivoted tothe arm I. The rack-bar is held into engagement with the pinion by abearingpoint, Q, on the inside of the post. The connection of the twowheels through the rackbar causes a conjunctive movement, and thenumbered spaces on both correspond. The shield m covers a portion of theface of the wheel D, and the shutter n is operated to open and close theorifice or window in this shield.

Thus but one number marked upon this wheel IOO mence with the wheelsdisplaying ajcipher, now press on the button 15, so as to project intothe path of the arm H, and carry the arm I r forward till the key comesagainst the said arm.

and then press the same back until the said arm I is arrested by the armH of the frame. This would show 15 on the computation-wheel D, and alsoon the indicator-wheel D. Now repeat the to-and-fro movement again andyou have 15 again on the peripheral face of theindicator-wheel D',and011 the computator-wheel D you have 30,the sum of the two movementsrepresented by 15, and so on, the individual number and sum appearing atthe openings through the shields. I contemplate the construetion of muchmore elaborate machines and a considerable number of buttons or keysrepresenting a large number of single numbers or individual amounts. Theessential mechanism is here presented, and the modifications would be byduplication. The backward movement of lever I raises the point of thepawl P on the spring a. and this depresses the inner end of the leverK,which causes the shutter a to close the vision orifice in the shieldm, which remains closed until the lever is returned to its formerposition. There can be no registration until the lever makesits fullbackward sweep; and this movement is neces sary to let the point of thepawl fall from the face of spring 12 to engage again the notches of theratchetwheel, by which the computation- I wheel D may be moved.

To set the register at zero, disengage the pawls and reverse themovement until the cipher is exposedto view.

Having fully described my invention,what I claim, and desire to secureby Letters Patent, 1s

1. The operating-arm I, provided with a series of push-buttonscorresponding to definite numbers, and the arresting-arm H engagedthereby in its backward movement, in combination with the rack-bar F,pinion G, and computationwheel D,wheel D, and operating-lever 1?, togive definite movements to said computation-wheel, substantially as setforth.

2. The combination of the computationwheel D with ratchet-wheel E, thepawl P,

pawl 00, operating-lever I, provided with the g adjustable buttons,arresting-arm H, rack-bar F, pinion G, indicating-wheel D, shields L andm, shutter n,weighted lever K, and traversing view-slide N, )rovidedwith projection eutering groove of said computation-wheel, substantiallyas set forth.

In testimony that I claim the foregoing as my own I aliix my signaturein presence of two witnesses.
